LUTHER B. BAILEY, OF LONDON, ONTARIO, CANADA.

OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 394,551, dated December 18, 1888.

Application filed August 27, 1887. Serial No. 248,082. (No model.) Patented in Canada .Tune 7, 1887, No. 26,898.

To all whom t may concern:

Be it known that I, LUTHER B. BAILEY, a subject of the Queen of Great Britain, and a resident of the city of London, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Oil-Cups, (for which I have obtained a patent in Canada, No. 26,898, June '7, 1887,) of which the following specification is a full, clear, and exact description.

This invention relates to an oil-cup for supplying oil or grease to rubbing-surfaces in order to diminish friction; and it consists of the improved construction and combination of parts of the sam^, as will be hereinafterf` ity rests on part of' the upper edge ot' the body i A. This compresses the springFand holds the cover C firmly at this point until the resermore fully described and claimed,

Reference being hadto the accompanying drawings, Figure 1 is a perspective View of an oil-cup embodying this invention. Eig. 2 is a longitudinal sectional view of the same. Fig. 3 is another sectional view showing the cover adjusted to permit of the refilling of the reservoir.

A designates the body of a lubricant-reservoir, from which reservoir the passage B extends and through which t-he lubricant is fed to therubbing-surfaces requiring lubrication.

C designates a cover formed with a flange, D. This cover rests close on the upper edge of the body A of the lubricant-reservoir, and the flange D, or its substantial equivalent,may be fit-ted either to the inside or outside or to both sides of the body of the lubricant-reservoir,

which locks and securely prevents displacement of said cover when properly adjusted.

E designates a screw or stud-pin passing through the cover C and screwing into the body of the lubricant-reservoir, which Inay be formed larger in cross-section at this point, as shown at a in Fig. 2 of accompanying drawings, to securely hold and retain said stud-pin. This stud-pin E is formed with a shoulder, E', between which and the upper face of the cover C a spring, E, is placed, which spring is for the purpose of tightly compressing the cover on the upper edge of the body A of the reservoir.

E2 is a shoulder, also formed on the stud-pin E, which shoulder binds on the body A of' the lubricant reservoir when the stud pin is screwed therein, and rigidly binds and holds said stud-pin in place and prevents any possibility of it becoming loosened when turning the cover t, or from any cause whatever.

G is a shield or case, which may be used to inclose and protect the spring F from dirt, &c., working in between the coils of said spring F, which would retard its operation.

ln filling this oil-cup, raise the cover t until the flange I) rises above the edge of the body A, and move said cover to the right or left. This brings part of the vflange over until Voir is refilled. Then turn the cover C back until it comes immediately above the position shown in Fig. 2, when this flange drops down on the side of the body A, when the flange D will securely hold and lock the cover in place to prevent a lateral movement, and the spring F will prevent a vertical Inovement,so that the cover will be securely held in place to prevent loss of the contents of the lubricant in the reservoir; and the shonlderE2, binding on the body A, rigidly binds the studpin E on said body and thereby completely prevents it revolving with the cover O, or from becoming displaced from any cause whatever.

Having thus described my invention, what I claim as new is- The body A, having a passage, B, in combination with cover C, formed with flange D, and having case G, stud-pin E, formed with shoulders E E2, and spring F, substantially as described, and for the purpose specified.

In testimony whereof I affix my signature in the presence of the two undersigned Witnesses.

LUTHER B. BAILEY.
